• Delivers clean bass and headroom for daily listening

Wiring Configuration:

This combo includes a Single Voice Coil (SVC) 4-Ohm subwoofer and a monoblock amplifier rated for 2-Ohm stability. For optimal performance and safe operation:

• Connect the subwoofer directly to the amplifier’s output terminals using high-quality 12 AWG or 10 AWG speaker wire.
• Since the subwoofer is SVC 4 Ohm, wiring is simple:

  Positive (+) on the amp goes to positive (+) on the sub.

  Negative (-) on the amp goes to negative (-) on the sub.

This setup will present a 4-Ohm load to the amplifier, which the APHF-1500D-H1 handles efficiently while delivering solid output for the sub’s 500W RMS rating.

Pro Tip:

To get the most out of your setup, use a 4-gauge amp kit for proper power delivery and grounding. Don’t forget to set your gains correctly with an oscilloscope or test tone to avoid clipping or distortion.
